A coded checklist and ecological indicator values of freshwater diatoms from The Netherlands

Abstract

This first comprehensive checklist of the diatoms from fresh and weakly brackish water in The Netherlands comprises 948 taxa, belonging to 776 species in 56 genera. The generaNavicula, which has a very wide ecological amplitude, andNitzschia, which has many pollution tolerant species, are most numerous. Each taxon is identified with a unique eight-letter code, to facilitate computer processing of data. Ecological indicator values for pH, salinity, nitrogen uptake metabolism, oxygen, saprobity, trophic state and moisture are presented.
